Yesterday, a Chechenyan pupil beheaded his history teacher. The murderer was taken aback by the presentation of Charlie Hebdo’s Mohammet portrayal. Apparently, he lived in a microcosm where it was unheard of that, first, this picture exists, and, second, that such pictures are totally unoffensive. It points to our larger cultural crisis in which Muslims and non-Muslims alike fall under the omerta du jour.
